Unequal Error Protection Raptor Codes
We design Unequal Error Protection (UEP) Raptor codes with the UEP property provided by the precode part of Raptor codes which is usually a Low Density Parity Check (LDPC) code. Existing UEP Raptor codes apply the UEP property on the Luby transform (LT) code part of Raptor codes. This approach …

GridSLAM on the RAPTOR autonomous vehicle
This thesis develops and applies GridSLAM on a small autonomous car-like vehicle for indoor environments. GridSLAM uses a particle filter to generate a discretized 2D occupancy map. This GridSLAM implementation uses sparse, shared, and lazy data structures to reduce memory usage and computation …

Raptor Use of the Idaho National Engineering Laboratory
<p>Raptors are high trophic-level predators, and thus sensitive to environmental change. I conducted a basic ecological study of raptors using the Idaho National Environmental Laboratory (INEL), in southeastern Idaho, between 1991 and 1993 to assess effects of human activity on the site. Results …

Landscape level raptor habitat associations in northwest Connecticut
I measured habitat characteristics at 21 barred owl, 30 northern goshawk. and 17 redshouldered hawk nest areas, and at 49 random areas within a 780 km2 area in northwest Connecticut. Measurements were taken at a macro ground level and from 1:12,000 and 1:40,000 black and white and 1:58,000 and …

Friends or foes? Blood parasite costs and defence abilities in young raptor hosts
… host nestling phase. I show that in a long-lived raptor, the common buzzard (Buteo buteo), nestlings infected with the blood parasite Leucocytozoon toddi display low transcriptional response to increasing parasitemia (density of parasite per host cells), moderate signs of parasite-induced tissue …

Cooperative DVB-H: Raptor-Network Coding Protocols for Reliable and Energy Efficient Multimedia Communications
… of cooperative wireless communication, Raptor application layer forward error correction (AL-FEC) and Network Coding (NC) is examined. Originally proposed for broadcasting over the Internet, the application of Raptor codes to wireless cooperative communications networks has been limited …

Factors influencing the timing of breeding in a range expanding raptor at two spatial scales
Range shifts and expansions have been recorded in a number of species and it is expected that as climate change proceeds it will result in more species joining this trend. A major concern with these shifts is the suitability of the receiving novel environments, for example, if these areas …

A Multi-Scale analysis of organochlorine pesticide contamination in raptor populations: research effort, historical trends, and current concentrations
… that species at higher trophic levels, like raptors, can act as valuable indicators of environmental pollutants. Raptors are quintessential apex predators, occupying top levels of the food chain in various ecosystems globally. Due to the well-known negative impacts of these pesticides on …

Raptor abundance and diversity and red-shouldered hawk ( Buteo lineatus) habitat characteristics on reclaimed mountaintop mines in southern West Virginia
Raptor abundance and diversity were compared between 4 treatments (grassland, shrub/pole, fragmented forest, and intact forest) over 3 seasons (migration, summer, and winter) on 3 mountaintop/valley fill mines in southern West Virginia. Habitat characteristics of Red-shouldered Hawks (Buteo …

Moult as a dynamic link in the annual cycle of birds: insights from seabirds and a long-distance migratory raptor
… quality as adults in a long-distance migratory raptor. The study of feather quality in birds is still in its infancy, but the few studies to date indicate that chicks compromise feather quality to minimise their nestling period. In addition, few studies have explored how moult strategies are …

On The Design Of Physical Layer Rateless Codes
… practical realization of rateless codes while Raptor codes are constructed by serially concatenating LT codes with high-rate outer low-density parity-check (LDPC) codes. Although these codes were originally developed for binary erasure channel (BEC), due to their rateless feature, they are …

Investigation of selected autophagic proteins and the effect of tPS1-GFP expression.

Quantifying national abundance changes of raptors across Botswana using repeat road surveys
Raptors are a group of carnivorous birds experiencing considerable population declines across the globe. Despite these declines, many raptor populations remain poorly monitored across most of their ranges and, as with most biodiversity, this is especially true in developing countries, including …

Identifying genes that are required for the maintenance of pancreatic ductal adenocarcinoma
… We identified mTOR, and to a lesser extent, Raptor and Rictor, as genes that are important for the maintenance of PDAC both in vitro and in vivo. In addition, we show that inhibition of mTOR and Raptor are synthetic lethal in that PDAC lines are sensitive to their inhibition, while …

Unraveling Molecular Mechanisms Underlying the Development of Unconventional T Cells
… study, we uncovered the roles of the molecules RAPTOR and PTEN in the thymic development of unconventional T cells. Capitalizing on genetic deletion of RAPTOR, we found RAPTOR-dependent mTORC1 signaling couples microenvironmental cues with metabolic programs to orchestrate the reciprocal …

Reduction of rework at a large aerospace manufacturer

Breeding success, prey use, and mark-resight estimation of burrowing owls nesting on black-tailed prairie dog towns: plague affects a non-susceptible raptor
Introduced pathogens such as the bacterium (Yersinia pestis) that causes plague can have far-reaching effects on native ecosystems that go beyond the mortality of infected individuals. We investigated the effects of plague, prairie dog town dynamics, and rainfall on burrowing owls (Athene …
